Will a contact sensor trigger an alarm or just send a phone alert?

Reviewer consensus

It depends on the system. Eufy, Tapo, and Hue Secure sensors can trigger an audible siren via their hubs; Aqara sensors can drive local Aqara Hub alarms or fire automations in HomeKit/Home Assistant. Standalone Wi-Fi sensors typically only push app notifications unless paired with an alarm kit.
